Help with this math problem?

For the following problem, the slope and one point on a line is given. Use the point-slope form to find the equation of that line. (Write your answer in slope-intercept form.)

(−1,−8), m = 3

Thank you!

y-y1=m(x-x1)
y-(-8)=3(x-(-1))
y+8=3x+3
y=3x-5 is your answer

(-1,-8) = (x1, y1)

Point Slope Form:
y - y1 = m( x - x1)

Substitute
y - (-8) = 3(x - (-1))
y + 8 = 3(x+1) ------ (Point Slope Form)

Slope-Intercept Form: Solve for Y
Y = 3(x+1) - 8
Y = 3x +3 -8
Y = 3x +5 -------- (Slope Intercept Form)
